Conversions MTA options
The MTA has a number of options relating to conversion operations. The most fundamental of these in Unified Configuration is
conversions, which replaces the legacy configuration
conversions file, being where conversions entries are stored. Additional options relating to conversion operations include:
string_pool_size_4, which respectively control the maximum number of conversion entries, the maximum number of personal conversion entries, and limits the total characters in conversions entries and in personal conversions entries.
original_channel_probe, which affect what information is used in certain mapping table probes; and
log_conversion_tag, which controls whether or not message conversion tags are included in MTA message transaction log entries.
